Parameters of Export Schemes?

I’m needing to do a lot of Rhino to AutoCad exports. However, I don’t know what exactly are the parameters of each export scheme. The Rhino help list the schemes, but not what they mean or what is included in the output file of each. Is there a list for this some where? Right now I need a to export elevation views of models and get 2D outlines of the elements to import in to AC. (like I do with Sketchup)
